Features

Technology
  • Metal enclosed unit for indoor installation and type tested
  • Insulated by SF6 Gas
  • Maintenance free and easy installation
  • Accident prevention technology using VI and power fuse
  • ON-OFF-Earth, 3-position load break switch
Safety
  • Approachable and safety operable in the presence of power cables
  • Clear indication of operation status via diagram on front panel
  • Fully automatic interlocking system
  • Internal arc withstanding is tested for operator safety in case of an accident
Durability and Usefulness
  • Metal enclosed tank is hermetically sealed
  • Operating the load break switch is possible in the front of the RMU
  • All switching operations can be safely made to all personnel due to the interlocking system
  • Recharging SF6 gas is not required throughout its service life
  • Remote operation is available while using the motor operating mechanism and RTU
Saving Cost
  • No maintenance is required other than replacement of the HRC power fuse after installation
  • Compact design that requires minimum space to install and local operation is the main advantage, especially where space is limited
